The suspension plate 1221a has a sheet-like structure of bending vibration, and its shape and dimensions correspond to the inner edge of the air guide assembly mounting area 1215. The hollow hole 1221b is provided so as to penetrate the central portion of the suspension plate 1221a for the flow of gas. In a preferred embodiment of the invention, the shape of the suspension plate 1221a is, but is not limited to, one of a square, a figure, an ellipse, a triangle, or a polyhedron. The cavity frame 1222 is arranged so as to be stacked on the fumarole sheet 1221, and its appearance corresponds to the fumarole sheet 1221.

The piezoelectric plate 1223c is housed in the insulating frame 1224 and is electrically connected to the piezoelectric plate 1223c by the conductive electrode 1225b of the conductive frame 1225. In a preferred embodiment of the invention, the piezoelectric carrier plate 1223a and the adjustable resonant plate 1223b are conductive materials. The piezoelectric carrier plate 1223a includes a piezoelectric pin 1223d, and the piezoelectric pin 1223d and the conductive pin 1225a are connected to a drive circuit (not shown) of the drive circuit board 123 to receive a drive signal (drive frequency or drive voltage).

The insulating frame 1224 can block between the conductive frame 1225 and the actuating body 1223 and avoid a short circuit in the circuit. Thereby, the drive signal can be transmitted to the piezoelectric plate 1223c. After the piezoelectric plate 1223c receives the drive signal, it is deformed by the piezoelectric effect to drive the piezoelectric carrier plate 1223a and the adjusting resonance plate 1223b to perform reciprocating bending vibration.

The adjusting resonance plate 1223b is arranged between the piezoelectric plate 1223c and the piezoelectric carrier plate 1223a and is used as a cushioning material between the two, so that the vibration frequency of the piezoelectric carrier plate 1223a can be adjusted. Basically, the thickness of the adjustable resonance plate 1223b is thicker than the thickness of the piezoelectric carrier plate 1223a, and the vibration frequency of the actuator 1223 can be adjusted by changing the thickness of the adjustable resonance plate 1223b.

As shown in FIGS. 7A, 7B, 8A, 8B and 9A, the fumarole sheet 1221, the cavity frame 1222, the actuator 1223, the insulating frame 1224 and the conductive frame 1225 are sequentially included in the piezoelectric actuator 122. It is installed so that it can be stacked. The piezoelectric actuator 122 is housed in the square air guide assembly mounting area 1215 on the base 121 and is supported and positioned by the positioning block member 1215b. The outside of the piezoelectric actuator 122 is surrounded by a gap 1221c for circulating gas. That is, the piezoelectric actuator 122 is surrounded by a gap 1221c defined between the suspension plate 1221a and the inner edge of the air guide assembly mounting area 1215. A resonance cavity 1226 is formed between the actuator 1223, the cavity frame 1222 and the suspension plate 1221a. An airflow cavity 1227 is formed between the fumarole sheet 1221 and the bottom surface of the air guide assembly mounting area 1215. The airflow cavity 1227 communicates with the resonant cavity 1226 between the actuator 1223, the cavity frame 1222 and the suspension plate 1221a via the hollow hole 1221b of the fumarole sheet 1221. As a result, the vibration frequency of the gas passing through the resonance cavity 1226 tends to be the same as the vibration frequency of the suspension plate 1221a, which promotes the Helmholtz resonance effect between the resonance cavity 1226 and the suspension plate 1221a. , The efficiency of gas transportation is improved.

As shown in FIG. 9B, when the piezoelectric plate 1223c moves away from the bottom surface of the air guide assembly mounting area 1215, the piezoelectric plate 1223c moves the suspension plate 1221a of the fumarole sheet 1221 to the bottom surface of the air guide assembly mounting area 1215. Drive away from. As a result, the volume of the airflow cavity 1227 rapidly expands, the internal pressure decreases to generate a negative pressure, and the gas outside the piezoelectric actuator 122 flows from the void 1221c and enters the resonance cavity 1226 through the hollow hole 1221b. The air pressure in the resonance cavity 1226 increases, creating a pressure gradient.

As shown in FIG. 9C, when the suspension plate 1221a of the fumarole sheet 1221 moves toward the bottom surface of the air guide assembly mounting area 1215 by driving the piezoelectric plate 1223c, the gas in the resonance cavity 1226 passes through the hollow hole 1221b. The gas in the airflow cavity 1227 is compressed, and the compressed gas is rapidly and abundantly ejected into the vent holes 1215a of the air guide assembly mounting area 1215 in an ideal gas state close to Bernoulli's principle. To.

The air guide assembly mounting area 1215 of the base 121 is communicated with the air-in groove portion 1214. The piezoelectric actuator 122 is housed within the square air guide assembly mounting area 1215 on the base 121. The drive circuit board 123 covers the second surface 1212 of the base 121. The laser assembly 124 is provided on the drive circuit board 123 and is electrically connected. The fine particle sensor 125 is provided on the drive circuit board 123 and is electrically connected. As a result, the outer cover 126 covers the base 121, the exhaust port 1216a corresponds to the intake port 1214a of the base 121, and the exhaust opening 1261b corresponds to the exhaust port 1216a of the base 121. When the operations shown in FIGS. 9B and 9C are repeated in the piezoelectric actuator 122, the piezoelectric plate 1223c vibrates in a reciprocating manner, and according to the principle of inertia, the pressure inside the resonance cavity 1226 after exhaust is lower than the equilibrium pressure. Therefore, the gas re-enters the resonance cavity 1226, the vibration frequency of the gas in the resonance cavity 1226 becomes the same as the vibration frequency of the piezoelectric plate 1223c, a Helmholtz resonance effect is generated, and a large amount of gas can be transported quickly.

As shown in FIG. 10A, the gas outside the gas detection module enters through the intake opening 1261a of the outer cover 126, passes through the intake port 1214a, flows into the intake path defined in the air-in groove portion 1214 of the base 121, and enters the fine particle sensor 125. Flow to the position of. At the same time, since the piezoelectric actuator 122 is continuously driven, the gas in the intake path is sucked. As a result, the gas outside the gas detection module can flow quickly and stably and pass above the fine particle sensor 125. As shown in FIG. 10B, the beam of laser light emitted by the laser assembly 124 at this time enters the air-in groove portion 1214 through the light transmission window 1214b and passes above the fine particle sensor 125. When the beam of the fine particle sensor 125 irradiates the suspended fine particles in the gas, a scattering phenomenon occurs and a projected light spot can be formed. The fine particle sensor 125 can perform calculations based on the projected light spots generated by scattering, and can acquire related information such as the particle size and concentration of suspended fine particles contained in the gas. The gas above the fine particle sensor 125 is continuously driven by the piezoelectric actuator 122, is introduced into the ventilation hole 1215a of the air guide assembly mounting area 1215, and enters the air out groove portion 1216.
